CNET's Greg Sandoval reported last month that several big-name sites have been sued in the U.S. District Court for using Flash cookies to spy on adults and children. At the center of this and similar suits are ad networks Clearspring Technologies and Quantcast that track your online activities even if you set your browser to block standard Web cookies.… Read more
The widget has been removed, but Wayne Huang, co-founder and chief technology officer at security firm Armorize, claims in an August 14 blog post that more than a half million of these parked domains are infected. Network Solutions says this figure is "inaccurate" but hasn't yet estimated the impact of the infection.
Regardless of the final … Read more
If you spend more than 2 hours a day peering at a computer display, you have at least a 50-50 chance of experiencing vision problems or other physical ailments related to your PC use. That's according to Dr. Wendy Strouse Watt, O.D., in her 2003 article Computer Vision Syndrome and Computer Glasses.
The advent of flat panels may have minimized the risk somewhat, but most office workers now spend more time each day at a computer than they did at the time of the study. In a series of articles on Computer Vision Syndrome, the American Optometric Association (… Read more
Google Docs wouldn't open my test PPTX file, but the service lets you create and edit presentations in the older PowerPoint PPT format, albeit without most of the desktop app's formatting options. You won't find much in the way of transitions, effects, and other advanced features in Google Docs, either. The best feature of Google's online presentation tool is its clean interface, which isn't a surprise considering the company behind the … Read more
Microsoft's first true browser-based versions of the venerable Word, Excel, and PowerPoint applications won't make you abandon the programs' full-featured counterparts installed your hard drive. But if you splurge for Office 2010, you may find yourself spending a lot more time working in your browser.
You probably already do some word processing and spreadsheet work using Google Docs, Zoho, or another such service. (I described the Web's best desktop-app replacements in a post last month.)
These services have offered first-rate word processing and spreadsheet programs that run in a browser and let you create, open, and store … Read more
But even then, Firefox and Chrome out-spell-check IE in a landslide.
The earlier post compared Firefox's built-in spell-check feature with the spelling checker in the free IE7Pro extension for Internet Explorer. It seems IE7Pro is no longer … Read more
Some people don't mind strangers rummaging through their Facebook friends lists, wall posts, status updates, and other details of their online selves. The rest of us attempt to control who has access to our Facebook information. The recent revamp of the Facebook privacy settings makes it simpler to adjust the many settings that determine whether and how people contact you, and how much of your information they can access.
Two free online scanners put your Facebook privacy settings to the test, though they take very different approaches to how they generate their ratings. ReclaimPrivacy.org gives you a Facebook … Read more
Google is listening.
As Marguerite Reardon and Tom Krazit reported on May 14 in CNET's Signal Strength blog, the search giant has swept up wireless-network addresses, along with other data its Street View vehicles have been collecting on their unprecedented world tour.
Google or some other company may have already plotted the location of your home or office wireless network, but you can make it more difficult for the next nosy megacorporation--or a neighbor or passing stranger--to discover your hot spot by disabling its Service Set Identifier (SSID).
By default, wireless access points transmit their presence to let wireless … Read more
But the fact is, much of the work we do in Word, Excel, PowerPoint, and other Office apps can be accomplished perfectly well using the basic features available in the Web-based equivalents to these and other desktop apps. Here's a quick look at three such services, all of which offer both free and paid versions. I'll also describe a bunch of specialty sites that can help smooth out your … Read more
Facebook is taking a lot of heat — again — about failing to protect the privacy of its users. (See Caroline McCarthy's The Social blog for a recap of the service's most-recent security gaffes.)
No matter what safety precautions Facebook and other social networks and Web sites take, eventually somebody's private data will become public, whether due to human error or a successful hack attack. Either way, your Web activities and the personal information you post to an online profile may be viewed by strangers, regardless of the account's security settings.
There are ways to minimize the risk … Read more
